This approach promoted by the WHO guidelines identifies five moments for HH (before patient contact, before aseptic procedure, after body fluid exposure, after touching a patient, after touching a patient's surroundings). These guidelines aim to encourage good HH compliance in the real world and recommend a multimodal HHP strategy making use of up to five components: 1) system change (for example, changing systems to ensure that alcohol-based hand-rub is readily available wherever and whenever needed), 2) training and education, 3) observation and feedback, 4) reminders in the hospital, and 5) a hospital safety climate.
